What perfume should I buy?

Hey I just wanted to ask about all the fragrances and which ones are worth buying. I was looking to buy another to add to my collection. I myself have:

Sweet Like Candy (1)

Moonlight (2)

Original Cloud (2)

Thank You Next (1)

Cloud Pink (1)

()= current quantity

If anyone has/had the following scents below or have smelt them before I would be super grateful to have some insight on them before I buy one.

REM, Mod Vanilla, Thank you Next 2.0, and Cloud 2.0. I bought rem for my sister Christmas 2022, but I don’t know what I’m comparing to. Thank you, I really appreciate the help!
